NEW YORK -LRB- CNN -RRB- -- A federal judge on Thursday threw out an author 's claims that Jessica Seinfeld , the comedian 's wife , plagiarized from her cookbook , but the judge left open claims of defamation against Jerry Seinfeld himself .

Jerry and Jessica Seinfeld attend an event in New York City in June .

`` This is a complete victory for Jessica Seinfeld , '' said Orin Snyder , Seinfeld 's lawyer .

Snyder said U.S. District Court Judge Laura Taylor Swain dismissed all claims brought against Jessica Seinfeld 's cookbook , `` Deceptively Delicious : Simple Secrets to Get Your Kids Eating Good Food . ''

In the lawsuit , filed in 2007 , author Missy Chase Lapine accused Jessica Seinfeld of taking ideas from Lapine 's cookbook `` The Sneaky Chef : Simple Strategies for Hiding Healthy Foods in Kids ' Favorite Meals . ''

Lapine 's cookbook was published in April 2007 , six months before Seinfeld 's book .

`` The court categorically rejected the claim that ` Deceptively Delicious ' infringed the copyright and trademark of the plaintiff 's book , '' Snyder said . `` The federal judge ruled that ` no reasonable fact finder could conclude ' that copying occurred here given that the works are ` very different ' and that Jessica 's book ` has a completely different feel . ' ''

But Lapine 's lawyer , Howard B. Miller , said his client may appeal the dismissal of her copyright and trademark claims , and will refile in state court claims against Jerry Seinfeld .

Lapine 's defamation claims against the comedian refer to a comment he made on the `` Late Show with David Letterman '' in 2007 , when he compared the fact that Lapine uses three names to the fact that assassins sometimes use three names , as was the case with Lee Harvey Oswald .

`` The claims against Jerry Seinfeld for defamation are still fully alive , '' Miller said . `` He just says he is joking ; we do n't think calling someone an assassin and a wacko is a joke . ''

`` I 'm up against a very powerful opponent , '' Lapine said in a telephone interview from her home in Westchester County , New York . `` Justice is not always served . ''

Lapine , a 45-year-old mother of two , said she has gone on to publish two other books , all in the `` Sneaky Chef '' series .
